behavior on whether IDLE was running under Aqua Tk rather than
under X11 Tk but that does not work since a framework build
could be linked with X11. For several releases, this test actually
differentiates between whether IDLE is running from a framework or
not. As a future enhancement, it should be considered whether there
should be a difference based on framework and any needed X11 adaptions
should be made dependent on a new function that actually tests for X11.)
